- Application filed, February Toiallv whom t may concern:

.Be it known that l, J-OHN B. Raviono, a subject of the King of Italy,and a resident of the borough of Manhattan, city, county, and StateofNew York, have inventedoelnew and useful Improvements` in`Colnbined-Vheel Fullers and Hub Caps, of which the ffollowing is aspecification. Y

This invention relates io an improved wheel puller adapted to be carriedby an automobile wheelfand also designed to' form an attractive hub capsinport therefor. i

rlhe object ofthe invention is to provide a hub extension which willbeeihcient inuse and attractive in appearance and at the same time maybe utilized as a wheel puller when it is found necessary to dismount theWheel.

Other objects of the invention will be apparent from the followingdescription when read in connection with the accompanying drawingsforming a part thereof.

Fig. 1 is a longitudinal section of a portion of the rear axle of anautomobile showing a portion of the rear wheel and associated f parts.

Fig. 2 is a similar view showing the wheel partly withdrawn from theaxle. n

Fig. 3 is a side elevation of the combined wheel puller and hubextension detached from the wheel.

Fig. 4 is a modified construction of hub extension and cap.

In Vthe drawings, 4 represents the rear axle housing which is flanged at6 and provided with a boss 8 in which is secured by suitablescrewthreads a retainer 10 which carries a roller bearing 12. Thebearing l2 supports the outer end of the axle shaft 14 which is taperturned as shown at 16 to fit the bore of the hub 18 of the wheel 20. Theaxle shaft carries a key 22 which fits in a key seat 24 formed in saidhub 18. The hub is provided with a radial flange 26 through which pass anumber of bolts 28. These bolts pass through suitable holes in thespokes of the wheel 20 and through aligned holes in the wallrof thebrake drum 30, nuts 32 clamping the flange 26 and brake drum to theWheel, as shown.

The hub 18 is formed with an extension 34 which is provided withscrewthreads 36 which engage similar threads 38 formed on the combinedwheel puller and hub extension 40. The extension 40 is formed with aflared tlange 42 which bears against the 2, 192,2. Serial No.,5`33,53,7.

flange 26 of the wheel hub,and said-hubextension is provided Awith aprojection 44 which maybe externally threadedwat 46 `to receivea hubcap,asshownmin Fig. 1, andis further formed with an inner chamber andabridge portion 50 having an extended boss integral therewith whichinternally threaded'at 52- A .Sheet 'metal 11.11.10 @er el" cover 54fits over ythe outer end of the proiaCtQnM-and iS 'Provided withthreads' 5.6 which engage the tlgireads 46 on theexterior Of Said heb@teman-40? The outer-end of the axle shaft 14 terminates in a threadedshank v15fto which af nut 17 V is secured tolto-ld the wheeland hubfirmly onV the taperedfend of the axle.

The normal position ofthe parts is shown in Fig. 1 in which it will beseen that the hub extension 40 covers the nut 17 and shank 15 of theaxle shaft and makes a neat finished appearance.

When it is desired, to remove the wheel from the axle shaft. the rearend of the car is jacked up and the hub cap 54 is removed from the hubextension 40, then the latter is unscrewed from the hub 34 of the wheelso that the nut 17 can be removed from the shank 15. This having beenaccomplished, the hub extension 40 is again screwed onto the hub 34 asshown in Fig. 2, and a bolt is threaded through the bridge portion 5()of the hub extension 40. When the end of the bolt 60 engages the end ofthe shank 15 a wrench is applied to the end of said bolt 60 so thatgreat pressure can be exerted to withdraw the wheel fro-m the taperedend of the axle shaft. It is only necessary to start or unseat thetightly engaging parts to allow the ready removal of the wheel. A shortbolt 60 sufliciently long to exert such starting or unseating movementcould readily be carried in place in the bridge 50 and enclosed by thecover 54, but usually the bolt 60 will be carried in the tool box of thecar. The threads 52 are of standard size so that the proper size of boltcan be readily secured in case the original is misplaced or lost.

In Figt 4 is shown a modified construction in which the cap 54 is fittedto the extension 40 and held in place by means of a screw bolt 70, thescrewthreaded shank 71 of which engages with the screwthreads 52 in thebridge portion 50 of the exten sion 40. The bolt 70 is provided with asuitably shaped heard 72 which is preferably hexagonal so thatV itY canbe easily gripped byr aV Wrench in order to turn the same; By means ofthis modified consti-uo tion the outer edge. of the extension 40 neednot be provided With'screivthreads but need only be provided with aVseat 75 for the reception ofthe `llange 76 of the cap 54.

-Modifications in the details of construction andkohanges of arrangementmay be made Without'departing from the invention as defined in theappended claims.

vl-Iavingthus described my invention what I claim as new and desire tosecure by Letto simulate an extended. hub, and providedV f at itsopposite end With `a removably mounted cap, said 'extension element alsohaving a bridge portion, said bridge portion being provided with acentrally disposed serewthreaded perforation in line with the wheel aXlewhen the said extension element is in place on the Wheel.

V2. A Wheel hub extension element' normally mounted upon Iand carried bythe Wheel, the said element being provided at one end With means forx,e1no\'abl \7 secur f ing the same to the Wheel and also with a flangesurrounding the said securing means,y the edge of the flangev beingadapted to Contact with the side of the wheel when in place to simulatean extended hub, said extension element also having a bridge portion,said bridge portion being provided with a centrally disposedscreivthreaded perforation in line with the Wheel axle when the saidextension element is in place on the Wheel. Y

In Witness whereof I have hereunto set my hand at Long Island City,countyv of Queens, State of New York, this 27th day of January, 1922.
